Ring Asymmetry and Spin in M87*

Vadim Bernshteyn, Nicholas S. Conroy, Michi Bauböck +263

Event Horizon Telescope (EHT) images of the supermassive black hole M87* depict an asymmetric ring of emission. General relativistic magnetohydrodynamic (GRMHD) models of M87* and…

Probing jet base emission of M87* with the 2021 Event Horizon Telescope observations

Saurabh, Hendrik Müller, Sebastiano D. von Fellenberg +282

We investigate the presence and spatial characteristics of the jet base emission in M87* at 230 GHz, enabled by the enhanced uv coverage in the 2021 Event Horizon Telescope (EHT) o…

Event Horizon Telescope Pattern Speeds in the Visibility Domain

Nicholas S. Conroy, Michi Bauböck, Vedant Dhruv +6

The Event Horizon Telescope is preparing to produce time sequences of black hole images, or movies. In anticipation, we developed an autocorrelation technique to measure apparent r…

Origin of the ring ellipticity in the black hole images of M87*

Rohan Dahale, Ilje Cho, Kotaro Moriyama +273

We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astro…

Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength

Razieh Emami, Matthew Liska, Koushik Chatterjee +15

Recent multi-wavelength observations of M87* \citep{2024A&A...692A.140A} revealed a high-energy -ray flare without a corresponding millimeter counterpart. We present a theoretic…

Dynamical Inference from Polarized Light Curves of Sagittarius A*

Angelo Ricarte, Nicholas S. Conroy, Maciek Wielgus +3

Polarimetric light curves of Sagittarius A* (Sgr A*) sometimes exhibit loops in the Stokes and plane over time, often interpreted as orbiting hotspot motion. In this work,…

The 230 GHz Variability of Numerical Models of Sagittarius A* II. The Physical Origins of the Variability

Ho-Sang Chan, Chi-kwan Chan

We continue our previous work, Chan et al. 2024, to investigate how variations in the electron temperature prescription parameter, , influence the -hour variability…

Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope

Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26

The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
